Inside truck cab under passenger side of dash

If you hear the relay, you need to pull the door panel and check power at the motor. Power there replace it. No power, the wires tend to break in the rubber boot at the front of the door jam.

only thing i can think of trying is to use the key to lock and then unlock the drivers door, this will disarm the security system/engine immobilizer

check resistor under dash by blower motor should be two screws holding it in or goto parts store and get new one and look under dash on passanger side

Hello shina.... when the blower motor stops working it is usually due to the A/C relay going bad. The good news is that this is a common item, easily replaced. Go to the autoparts store and get a new one. Then find the old one under the dash to the right of the steering column. Unplug the old and plug in the new. Joe

Thanks for choosing Fixya!

You should start by checking your fuses under the dash. Should be a small panel under the dash or on the side of it. The panel has a legend which shows the position and title of each fuse.

Fords systems will still blow air even when off. does the clicking get quieter wehn off?

also, you can get it to stop blowing by turning on the recirculator. its a button with a car on it and a u-shapped arrow on the ac controls in dash. IF it stops then then something is in the housing and the fan is hitting it.

Set your idle speed to mfg recomindation if that doesnt help check the dash pot that is what keeps the engine from stalling at sudden speed reduction

do you have spark? How do you know if your timing belt is good? sometimes it doesnt break just shed the teeth which could be missing under the crankshaft. The best way to check is to have two people. have one try to start the car and see if the camshaft is actually spinning. The crankshaft will always turn but if the teeth are gone on timing belt this would cause the belt to stay in one position not moving the camshaft. so if you can remove the upper timing belt cover and do this quick inspection with someone that will tell you for sure. if it does look like it is spinning then by hand turn engine very slowly with plug coil wires removed. and make sure teeth are all there. It couldve jumped timing. (valve timing)

Changed the starter and solenoid one time. Cranked and started two times normal. The third time it did not crank, just a clicking from the dash. Checked where the clicking was coming from and found out the solenoid on the fire wall was it. Changed that part but it still did not crank just clicked. There are two soleoinds on this truck, one on top of the starter and the other one in front top of the fire wall. There the battery cables connect to that solenoid to the starter and the alternter. The truck has power to everything, just will not start.
